Hi! I''ve my Xen server setup with Xen 3.2 built from sources and 2.6.18 custom kernel from mercurial. I''ve got an etch HVM domU working fine, but now Im''m trying paravirtualization. I built a custom 2.6.24.2 vanilla kernel according to http://wiki.xensource.com/xenwiki/Kernel.org_Linux_on_Xen but I can''t see the console. I added console=xvc0 to the extra section (I don''t have hvc0, is it normal?) but I can''t see anything. I can also see these lines in the xm dmesg: (XEN) *** Serial input -> DOM0 (type ''CTRL-a'' three times to switch input to Xen) (XEN) Freed 96kB init memory. (XEN) traps.c:1946:d1 Domain attempted WRMSR 00000404 from 00000040:00000001 to ffffffff:ffffffff. (XEN) traps.c:1946:d1 Domain attempted WRMSR 00000408 from 00000000:00000001 to ffffffff:ffffffff.
